To @ZZ 'u1/1.0m t may concern: i

Be it known that l, SVEN 0. Mriznno, a

citizen of the United States, residing at Providence, in the county ofProvidence and State oi' Rhode sland, have invented certain new anduseful Improvements in Bracelets, ot which the following is aspecilication. t

rlhis invention relates to improvements in l0 bracelets moreparticularly tothe extensible type of bracelets constructed from aseries of guide links and slide links, and the object of this inventionis to Vprovide 1n such a bracelet a slide link `having a tongue membersupporting .a coil spring thereon.

which spring 'serves to normally hold the'.

guide links in contracted position. u

A further object or the invention 1s the provision of means whereby thewalls of theguide link closing member are ladapted to,

lit inside ot the walls of the body portion for the purpose ofreinforcing these walls and also to serve as a spacer for -determining adeiinite space w'ithinfthe guide member to insure a free action of theslide link and spring therein.

The nature and advantages of the invention will be better understoodwhenv the following detailed description is taken in connection with theaccompanying drawings, the invention residing in the combination andarrangement of parts as claimed. i

ln the drawings forming part of this specilication, like numerals ofreference inwherein Figure 1 iS an edge View Otan expansible braceletmade of my improved construction ot guide links and slide links.

Figure 2 is a Jface view showing a number of the links as connectedtogether and in contracted position.

Figure 3 is a perspective view of the body portion of one of the guidelinks with its closing member removed.

Figure 4 is a perspective view of the closing member for the body of theguide link, removed.

Figure 5 is a perspective view of the slide link, showing thelongitudinallydisposed tongue within the frame thereof.

Figure 6 is a face View from the under side of the links, showing anumber as condicate similar parts in the several views and 192e. 'serialNo. 566,923.

nected together and in' extended position, the walls of the closuremember being Shown in section with its closing plate removed. v

Figure 7 isan edge view of the links in expanded arrangementillustrating the end walls of the closure member as extending inside ofthose of the body member.

Figure 8 is an enlarged end vienT sectioned on line 8 8 of Figure 6inwhich the side walls of the closure member are shown `as extendinginside/of thel side walls of the body member,l the edges'of` the latter`being rolled o-ver the shoulders of the former.

Figure 9 is a view of the underside of' a pair of links,- showing theside walls of the body member rolled ov'er the shoulders of the innerclosing member.

With reference `to the drawings, '10 desig nates the guide members ofthe bracelet, the bodies oi which are preferablydrawn up intorectangularlyshaped vshells having side walls 11 and end walls 12. Eachof these end walls is preferably vprovided with two deep slots 13 oneither lside of the center thereof. y

In order to 'close the bottom of this rectangular outer shellmembenl'have provided a correspondingly shaped vclosure member 1 4, thesize being such that both its, side walls 15 and its end walls 16 'areadapted to fit closely inside of the outer body thus performingtwoufunctions; first, for stifl'ening those of the' 'outer shell andsecond, these in-Y wardly-extending walls on the closure member arearranged to bottom in the outer member to serve as spacers to definitelydetermine the proper space between the shell for the unrestricted actionof the slide link and spring presently described.

The end walls 16 of this closure member are also slotted at 17 toregister with the slots 13 in the outer member to permit the passage ofthe slide-link therethrough.

In order to secure the closure member to the body member the edges 18 ofthe outer body are rolled over the shoulders 19 of the closure memberconnecting these parts permanently together.

In order to connect the guide links together so that they may be drawnslightly apart for the purpose of extending the length of the braceletto permit it to be readily passed over the hand of the wearer, I haveformed a slide link 20 Which is in the shape oit a rec tangular framehaving side bars 21Y and end bars 22. These side bars are arranged toextend through the slots 13 and 17 in the adjacent end Walls of theadjacent guide links, and the end bar 22 of each of these links engagesthe inner surface of a guide link. The opposite end bar of the slidelink is provided With a central longitudinally-extending tongue or nger23, which nger serves to support one end of the coiled spring 24 whichis coiled about it, which spring is arranged to act between the innerWall of its guide link and the end bar 22 ot' the slide link, therebyhaving a tendency to normally hold the adjacent ends of the adj acentlinks together, but at the same time permitting these links to be drawnapart for a certain distance, Which distance is limited by the outer endof this finger 23 bringing up against the inner end wall of its guidelink. v Y

The inner closing plate 25 of the closure member 14 is preferably domedslightly to provide Working room for the coiled spring 24. L

The parts of my improved bracelet may be formed of any suitable materialand by its construction the bracelet isv made very strong and durable,asthe walls of the outer shell are `reintorced by those of the closuremember thus permitting this outer shell to be formed of very thin stockvvhichv is of particular advantage especially when the same is made of`precious metal. Then again by Jforming the spring-centralizing finger23 on the slide link, the same is adapted not only to support and holdthe spring in central position and out of- Working contact With theWalls of the body portion, but it also serves to limit the expandingaction of this slide link by bringing upagainstthe inner end Wallthereof and so prevent undue pressure being brought upon the coiledspring 24 due to exerting an excessive spreading tension on thebracelet.

My improved bracelet is very handsome in A appearance, simple andinexpensive in construction, and is very\ strong. and durable.

The foregoing description is directed solely towards the constructionillustrated, buty I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which thedeviceis susceptible, the invention being defined and limited only'by theterms of the appended claims.

I claim:

1. In -an expansible bracelet, a series ol' cap for the back of saidbody having Walls Y adapted to fit dovvn inside of said body to stiftenthe same and limit their closing inovement, and a rectangularframe-shaped slide link extending through the slots in said body Wallsforming connecting members for said guide links, said slide link havinga central longitudinally extending tongue, and a coiled spring supportedon said tongue for` normally holding the guide links in contractedposition.

3. In `an eXpansible bracelet,.a series of guide links connected by arectangular holloW frame-shaped slide link, said sli-de link having asingle central longitudinally-disposed tongue connected to one of thecross bars and extendingtovvards the center of the frame, and a coilspring supported on said tongue for normally holding the guide links incontracted position, the end oi' said tongue serving as astop to limitthe'opem'ng movement of the links.

In testimony whereof I aiiiX my signature.
